HEADER FOR SECTIONAL STEAM-GENERATORS.

SPECIFICATION forming part of Letters Patent 0. 704,968, dated July 15, 1902.

I Application filed December 12,1901. Serial No. 85,575. (No model.)

To all whom it may concern.-

Be it known that I, JAM S H. ROSENTEAL, a subject of the King ofGre'at Britain, residing at LOndOn EngIand, have invented certain new and useful Improvements in Headers for Sectional Steam-Generators, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to sectional steamboilers in which a series of water-tubes are connected at their opposite ends to headers of serpentine or corrugated shape,.wh ich are arranged in line to form a group. The watertubes are generally used in an inclined position and the connected headers either placed vertically or at right angles with the inclined tubes.

The invention consists in forming the opposite faces of such headers at each corrugation of zigzag shape to obtain surfaces in the line of the axis of the water-tubes at right angle thereto to facilitate access to the tubes for purpose of inspection, insertion, removal, or repairs to all or any individual tube, which are usually arranged in clusters at each corrugation in the header.

In the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a portion of a header, showing zigzag or stepped faces provided at right angles to the axis of the clusters of connected tubes; and Fig. 2, a face view showingthe corrugated or sinuous form of the header with an end view of the connected clusters of tubes.

Theou'ter face at each step in the header is constructed with an opening, as shown in Fig. 2, through which moved, replaced, or repaired, and provided with a cover or plate 13. This zigzag or stopped construction upon the opposite faces of the header and the arrangement inline with the axis of the water-tube provides for the more convenient removal, insertion, or clearing of the tubes and' the manipulation of the tools designed for such purposes than in the straightiform of the faceSQas'usually made.

Having thus fully described my invention,

the tubes A maybe rewhat I claim, and desire to secure by Letters Patent, is- I A corrugated header for sectional watertube steam-generatorsfhaving its opposite faces constructed in zigzag or stepped form at each corrugation with surfaces at right angle with the line-of the axis of the con- .nected water-tubes, as set forth.

In testimony whereof I aflix my signature in presence of two witnesses. 1
